MARCELLUS L. WHITOOMB, OF COLDWVATER, MICHIGAN.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 328,265, dated October13, 1885.

Application filed March 9, 1885. Serial No. 158,179. (No model.)

To all whom it may concern.-

Be it known that I, MAROELLUS L. WHIT- COMB, a citizen of the UnitedStates, residing at Goldwater, in the county of Branch and State ofMichigan, have invented certain new and useful Improvements inWindow-Screens; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

The object of my present invention is to construct a screened frame fora window to exclude insects, which will be cheap, neat, and durable, andmay be readily adjusted transversely to accommodate the varying Widthsof windows.

In the drawings, Figure 1 is a rear elevation of my invention, showingthe wings B B as extended by dotted lines. Fig. 2 is a front elevationof Fig. 1. Fig. 3 is an enlarged top view of the adjusting parts. Fig. 4is an enlarged section through the screen and frame, showing the mannerof attaching the screen to Fig. 5 is an enlarged detached view of themetal plate of the wings B. Fig. 6 is a view similar to Fig. 3, havingthe plate P removed therefrom.

The screen-frame consists of the stiles A A A A, which are halved orotherwise secured together at the ends.

The frames are made up in a uniform size; but as windows Vary in width Iplace over the vertical stiles A A the extensible moldings or wings B B,as shown in Figs. 2 and 6. The wings on the back side are'provided witha rib or stop, I), (see Figs. 1 and 4,) which limit the closing up orbringing together of the wings, as said stop engages with the edge ofthe stiles A of the frame, as shown in Fig. 1. The length of the wings BB is equal to the height of the screen-frame; and to the ends of thewings I attach the metal plates 1?, by means of screws or nails throughthe ears D, as shown in Figs. 2 and 5. Said plates are provided with thewebs it, formed a right angle to the face of said plates. In tln ends ofthe vertical stiles A A, I out wit] a saw or like tool the channels r r,(see Figs 3 and 6,) and in one of said channels th webs h lie when theparts are together, a: shown in Fig. 3, thus forming a sliding guide forthe wing or wings B B. By forming the two channels 1" r the moldings orwings B I may be attached on either side of the screenframe.

I form integral with the plate P the spring 8, and employ two suchplates with springs uponthe right-hand side wing, using the plates Pwithout said springs upon the oppo= site wing, as shown in Figs. 1 and2. The springs 88 are designed to lie within the channel of thewindow-frame, between strips on ,the window-case, or within the channelsof the window-stops, and by the pressure of said springs thescreen-frames are held when elevated. The springs are bent over at rightangles to the plate P, and when in position the outer ends of thesprings rest upon the rib or stop I) of the wing B.

As a means for holding the wing or wings when adjusted, I pass throughthe vertical stiles of the screen-frame, near the center, the screws 0G, as shown in Figs. 1 and 3. Said screws when inserted pass throughsaid stiles and enter the moldings or wings B B, thus securing the partswhen adjusted.

To extend or close the wings, the screws C G are first withdrawn, whenthe wings may be readily moved by pulling or pushing transversely, asand for the purposes hereinbefore stated.

I am aware that screenframes having side extensions have heretofore beenpatented, and do not claim, broadly, such subject-matter.

vention, what I claim as new, and desire to secure by Letters Patent,is-

1. In combination with the vertical stiles of a screen-frame, theoverlapping sliding wings attached to said stiles by means of the metalplates having the ears, the webs, and

Having thus fully set forth my present ini springs formed integral withsaid plates, the Whole operating in the manner substantially asspecified.

2. In combination with the vertical stiles of a window-screen, thesliding wings adj ustably secured to said stiles by the screws 0 O, asspecified, said wings having longitudinal flanges, the metal platesattached to said wings and having ears and springs formed integraltherewith, substantially as specified. 10

In testimony whereof I affix my signature in presence of two witnesses.
